Abstract
The invention provides a temperature control device for a Raman spectrometer and belongs to the technical field of temperature regulation. The temperature control device comprises a temperature control box and a control system; a cyclone is arranged inside the temperature control box; two outlets of the cyclone are connected with a heater and a refrigerator respectively; the heater and the refrigerator are connected with a selector valve respectively; the control system comprises a temperature sensor; the temperature sensor is connected with a controller which is connected with the selector valve. The temperature control device is capable of automatically releasing cool air or hot air for regulation according to the internal temperature of the Raman spectrometer according to the double-circuit cyclone temperature control technology, and therefore, the internal temperature of the Raman spectrometer is kept in an appropriate range to ensure normal operation of the Raman spectrometer.
Description
Technical field
The present invention relates to Oil Temperature Controlling Technigue field, in particular to the attemperating unit for Raman spectrometer.
Background technology
The existing attemperating unit for Raman spectrometer can only releasing cool air, for cooling, and the function that do not heat up, makes the environment that Raman spectrometer can not adaptive temperature acute variation.
Summary of the invention
The object of the present invention is to provide the attemperating unit for Raman spectrometer, can only be used for cooling to solve the existing attemperating unit for Raman spectrometer, and the problem of the function that do not heat up.
The present invention is achieved in that
This attemperating unit for Raman spectrometer comprises temperature control box and control system.Temperature control box inside is provided with cyclone, and 2 delivery outlets of cyclone are connected with respectively well heater and refrigerator, and well heater is connected with selector valve respectively with refrigerator.Control system comprises temperature sensor, and temperature sensor is connected with controller, and controller is connected with selector valve.The cyclone of this attemperating unit is the cyclone of divided gas flow.Anhydrously enter from the input port of cyclone without oily pressurized air, enter respectively refrigerator and well heater after the shunting action of cyclone, the air that enters refrigerator is cooled to negative 10 degrees Celsius, and the air that enters well heater is heated to 100 degrees Celsius.Temperature sensor monitors the internal temperature of Raman spectrometer, and relevant data are passed to controller, and controller to selector valve transmitted signal, completes the release of cold air or hot gas according to the data that receive, and whole Raman spectrometer is carried out to temperature adjusting.
Further, between well heater and selector valve and between refrigerator and selector valve, be provided with variable valve.Flow and the pressure of the gas that variable valve can regulating and controlling passes through.
Further, selector valve is connected with the tracheae for releasing cool air or hot gas, on described tracheae, is provided with digital pressure gauge, to detect gaseous tension situation.
Further, the delivery outlet of tracheae is provided with sound suppressor, to reduce the noise of emitting when air release.
Further, temperature sensor is platinum resistance temperature sensor.Platinum resistance temperature sensor can be that 4-20mA electricity stream number is input in controller by temperature transition, for controller judgement.Meanwhile, platinum resistance temperature sensor is highly stable, is not easy to be subject to environmental change impact, and test effect is more accurate.
